Hi,
I have a 97 20VT with a Scorpion alarm.
It hasn't gone off in the year I've had it but the key fob hasn't been operating the central locking either.

Is it possible that it is just turned off? I have 2 small keys, one that goes on the siren in front of the airbox. The other is a small filing cabinet key with a black cover. Is that related to the alarm and where does it go?

Any help will be gratefully received.

3 more things.

I've tried the siren key in both key positions and nothing changes. The alarm doesn't go off and the fob still does nothing.

The bonnet closed pin sensor is missing.

Looking up above the fusebox I can't see anything like a Scorpion black box. I'll try taking the dash side cover off next weekend.

When you press the left button on the remote, does the small red LED light up? If not, replace the battery.

All the key does is turn the siren off, it does not disable the alarm. If you turn the key anti-clockwise and remove it, siren is off. Clockwise is on.

The slider switch on the remote controls whether the interior sensors at the bottom of the A pillars are active or not. If the remote/alarm works, the alarm will peep (and indicators flash) twice if sensors are off, three times if on.

Chances are, if it's a '97, that the alarm box is above the glove box and easily accessible by removing the passenger dash end panel.

It lights and I put a new battery in yesterday

Thanks. I guess the main box is doing nothing.

Thanks for the info.

That is handy. I looked up from the driver's footwell and couldn't see anything there. The hole in the glovebox where the key switch might be is blanked off but I guess that is only for the META alarm.

No, the glove box hole is for the factory fit alarms for European market, UK models had alarms fitted at point of entry or somewhere before appearing at the dealers (horrible thought: maybe the dealers fitted them?)

Maybe you just have a loose connection to the alarm box?

I can't remember now, but if you lock/unlock a door and central locking is working (a separate system controlled by a box under the driver's seat) doesn't the other door lock/unlock too? If you press the door lock button on the dash when inside the car, do the doors lock?

Hi Dave,
The central locking via the door locks and the lock button still works but that is a car function and not an alarm one as far as I know.

The system apparently just stopped working one day. A Fiat dealer suggested that a new alarm would be required but I would prefer to keep it original.

Yes, alarm is just an add-on to sound a siren and flash the indicators. I picked up a new unused 918U kit (with choice of Alfa or Fiat logo on the fob) from eBay some time ago, they do pop up occassionally (system is 10 years old now) but why not just get a new alarm, they're not that expensive? Hopefully you'll get an answer when you find the alarm box under the dash.

I've had a look around again today.
There is nothing behind the passenger side, but I think the header connector for the META alarm is there so somebody could've saved themselves some work.
Behind the drivers side panel is a load of wound up wire for the ultrasonic sensors and there's a third connection that ends in a taped up loom above the fusebox.
I guess the Scorpion box comes off here but it is really hard to see.

Does the Scorpion alarm box connect via a black single row header connector with about 15 pins and about 10 actual wires?
If yes I don't have an alarm any more.

I'm wondering if hooking a META alarm in behind the glovebox might be an easy fit?

All the wiring for both the scorpion and the meta alarm module are above the fuse board drivers side, there's nothing on the passenger side connected with the alarm except the movement sensor on the dash by the tweeter.

That seems to tie in with where the wiring from the sensors went.

Do you ever get spare Scorpion alarms off any of your cars? I think mine's been nicked by a well intentioned Fiat mechanic.

I do yes, let me check after the weekend as I'm sure I've a couple of modules in stock with key fobs, should just be a case of plug and go but as we all know with these cars sometimes it's no that simple.

Thanks,
I have one key fob but it would be great if you have another one to go with the alarm box.
